As lawmakers work to finalize an immigration law rewrite that would provide a path to citizenship for many of the undocumented already here, fewer than half of all Americans say the undocumented should be eligible to become citizens, according to a survey run by the Pew Research Center.

While 71 percent of respondents to a new Pew poll say undocumented immigrants should be able to stay in the U.S. as long as they meet certain requirements, 24 percent say they should be eligible for permanent residency. Only 43 percent say undocumented immigrants should be eligible for citizenship.

Another 27 percent of respondents say undocumented immigrants should not be allowed to stay in the country legally.

Pew’s findings come as eight senators work to finalize a bill that provides undocumented immigrants with a path to citizenship, Bloomberg’s Julie Hirschfeld Davis reports. The bipartisan Senate group is pushing to unveil its measure the week of April 8.

Approximately 11 million undocumented immigrants currently live in the U.S.
